-First things first - Nexenta is NOT debain with opensolaris kernel, it'opensolaris with a few debian tools, like apt. It's anoying for a linux admin, because ps ax is ps -ef, mount -t is mount -F, ifconfig barfs without parametrs etc. +====== Nexenta ====== 
-But at least bash is the default shell :)+

 Other changes, that requires some adjusting to - SMF. Yes, init.d and inittab are history.

 Few tricks: if format complains about not being able to relabel a disk that is in use, simply export NOINUSE_CHECK=1. Also when creating a zpool from slices, it complains that s0 overlaps with s2 (which should be that way, if I understand slices corectly), but we can simply use zpool create -f. After you created your zpool and zfs volumes to your desire, be sure to check zfs get all <name> and check what all can you set on them. I found compression=on and atime=off very userful. Also set snapdir=visible if you plan to offer backup history via shapshots. It's amazingly simple :) Few tricks: if format complains about not being able to relabel a disk that is in use, simply export NOINUSE_CHECK=1.
